It's just hours to go now for International Yoga Day, a truly multinational event spearheaded by Prime Minister Narendra Modi. More than 30,000 people are likely to be present on Rajpath in New Delhi to create a new Guiness record for the largest single yoga assembly. Events are also planned in cities across India and countries around the world. Records may well be broken, good health may be given a big push but the question we're asking is this: What is Yoga Day truly about - spirituality, physical fitness or an international push of India's cultural agenda?
